Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically to an electrical control cabinet that is easy to maintain. Background Technology

[0002] In industrial production and automation control, electrical control cabinets are core equipment that houses electrical components and cabling, and their ease of maintenance directly impacts equipment operation and maintenance efficiency and production continuity. However, existing electrical control cabinets generally suffer from maintenance difficulties, specifically in the following aspects: The rear panel and internal support plate of existing electrical control cabinets are mostly rigidly fixed to the cabinet frame with multiple sets of bolts, lacking a flexible connection structure. During maintenance, tools are needed to disassemble each bolt one by one, which is not only time-consuming and labor-intensive, but also prone to obstruction due to bolt corrosion and confined space. Especially for electrical components deep inside the cabinet, the entire outer structure must be removed to access the faulty part, further increasing the difficulty of maintenance and prolonging equipment downtime.

[0003] In existing control cabinets, the connections between support plates and side plates, as well as between components and support plates, mostly rely on a single fixing method, lacking dedicated quick-connect components. When a component fails, it is necessary to simultaneously disassemble surrounding related components, which can easily cause wiring strain, component damage, and even secondary faults. Furthermore, after disassembly, traditional connection structures make it difficult to quickly and accurately reposition components, requiring repeated calibration, further reducing maintenance efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an electrical control cabinet that is easy to maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An electrical control cabinet that is easy to maintain includes: a cabinet body, a door panel 1 on the front side of the cabinet body, a door panel 2 on the front side of the door panel 1, a support frame inside the cabinet body, and rear side panels 1, 2, and 3 are bolted together on the rear side of the support frame from top to bottom. I-frames 1 and 2 are bolted together on the front side of the support frame corresponding to rear side panels 1 and 3. A connecting component is provided between I-frames 2 and 1. Sheet metal parts are bolted together on I-frames 1 near the rear side panel 1. Fixing parts 1 are provided on both the left and right sides of the front side of the rear side panel 2. Fixing parts 2 are bolted together on the front side of the rear side panel 3 and the front side of the rear side panel 1. The rear side panel 1, rear side panel 2 and rear side panel 3 are all designed to be detachable. The front side of the upper and lower fixing parts 2 is respectively provided with support plate 1 and support plate 2, which are used to place electrical components. The connecting components include: a support frame and a support bend plate. The left and right sides of the support frame are fixedly connected to the support frame by bolts. A support plate three is fixedly installed on the upper part of the support frame. U-shaped parts are installed on the left and right sides of the lower part of the support frame. Multiple sets of support columns are installed between the U-shaped parts on the left and right sides. The upper support bend plate is fixed to the fixing part one by bolts. The lower support bend plate is fixed to the fixing part two by bolts. The U-shaped parts are connected to the fixing part one by pins. The connecting assembly is used to connect support plate three and support plate two through support bend and support column. At the same time, the U-shaped part and the fastener one make support plate three and support plate two detachable from rear side plate two and rear side plate three. Support plate three is used to place electrical components.

[0006] Preferably, the pin is configured as a release pin, which includes a handle and a pin shaft. The pin shaft is spring-loaded, which facilitates manual operation and allows for the disassembly of the connection between the U-shaped part and the fixing part without tools.

[0007] Preferably, support plate one, support plate two and support plate three are all provided with guide rails. The guide rails are used to install electrical components. The guide rails are detachably fixed to the support plate by bolts, and are used for sliding installation and replacement of electrical components.

[0008] Preferably, the support frame is provided with detachable cable trays on both the left and right sides. The cable trays are connected to the support frame by plastic clips and are used for laying and managing cables.

[0009] Compared with the prior art, this utility model provides an electrical control cabinet that is easy to maintain, and has the following beneficial effects: The connecting assembly utilizes a composite structure consisting of bolted support plates and pin-connected U-shaped components. Coupled with a spring-loaded release pin, the U-shaped component and the fixing component can be quickly separated manually without any tools. Furthermore, the bolted connection between the support plate and the fixing component can be selectively disassembled without requiring complete disassembly of the entire connecting assembly. This reduces disassembly time during single maintenance compared to traditional structures, lowering the workload for maintenance personnel, making it particularly suitable for frequent maintenance scenarios.

[0010] The connecting components, through the cooperation of the support frame, support bend, and support column, enable independent and detachable connections between support plate three and support plate two, and rear side plate two and rear side plate three, respectively. Combined with the layered rear side plate design of the cabinet, this forms a modular support system. During maintenance, only the connecting structure of the corresponding module can be disassembled according to the faulty location, without touching other normal components. This allows for localized troubleshooting, avoiding the efficiency loss caused by complete disassembly and reducing the risk of secondary failures. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-5 As shown, this embodiment of an electrical control cabinet for easy maintenance includes a cabinet body 1. The cabinet body 1 serves as the external protective structure for the entire equipment, providing a stable installation and protective environment for internal components. A door panel 102 is provided on the front side of the cabinet body 1, and a second door panel 101 is provided on the front side of the first door panel 102. This double-door design enhances the dustproof and protective performance of the cabinet body 1, and allows for individual opening according to maintenance needs, avoiding excessive exposure of internal components when the entire door is opened.

[0015] The cabinet 1 contains an internal support frame 2, which is the core load-bearing structure of the cabinet 1, used to support the rear side panels, connecting components, and various support plates. From top to bottom, the rear side of the support frame 2 is bolted to three rear side panels: rear side panel 105, rear side panel 104, and rear side panel 103. This bolted connection ensures the stability of the side panel installation, while the detachable design facilitates subsequent deep-level maintenance. On the front side of the support frame 2, corresponding to rear side panels 105 and 103, are I-frames 301 and 302, respectively. These I-frames provide a precise installation reference for the connecting components 4.

[0016] A sheet metal part 303 is bolted to the I-frame 301 near the rear side plate 105. The sheet metal part 303 provides auxiliary support and protection, preventing stress concentration at the connection between the rear side plate 105 and the I-frame 301. Fixtures 405 are provided on both the left and right sides of the front of the rear side plate 104. Fixtures 306 are bolted to the front of both the rear side plate 103 and the rear side plate 105. Fixtures 405 and 306 serve as the mating structure for the connecting assembly 4, providing a reliable connection point for the installation of the support plate.

[0017] Support plates 305 and 401 are respectively installed on the front of the two fixing parts 306 on the upper and lower sides. A connecting component 4 is installed between the I-frame 302 and the I-frame 301. The connecting component 4 includes a support frame 304 and a support bend 402. The left and right sides of the support frame 304 are fixedly connected to the support frame 2 by bolts to ensure the overall stability of the connecting component 4. A support plate 404 is fixedly installed on the upper part of the support frame 304. The support plates 305, 401, and 404 together form a three-layer component mounting platform, which can be arranged in layers according to the component specifications to improve space utilization.

[0018] The lower left and right sides of the support frame 304 are provided with U-shaped components 403, and multiple sets of support columns are arranged between the U-shaped components 403 on the left and right sides. The support columns enhance the structural strength of the U-shaped components 403 and provide auxiliary support for the second support plate 401. The upper support bending plate 402 is fixed to the first fixing component 405 with bolts, and the lower support bending plate 402 is fixed to the second fixing component 306 with bolts. The U-shaped components 403 are connected to the first fixing component 405 with pins. This composite connection structure not only ensures the connection stability between the support plate and the side plate, but also provides a basis for quick disassembly.

[0019] The left and right sides of the support frame 2 are equipped with detachable cable trays. The cable trays are connected to the support frame 2 by plastic clips. The cable trays are used to neatly lay cables and avoid messy lines affecting maintenance. The plastic clip connection method facilitates the quick disassembly and installation of the cable trays.

[0020] In some examples, the pin is configured as a release pin, which includes a handle and a pin, with the pin being a spring-loaded structure. This design allows for the separation of the U-shaped part 403 from the fixing part 405 without the need for tools, significantly improving disassembly efficiency, and is especially suitable for frequent maintenance scenarios.

[0021] In some examples, support plate 1 (305), support plate 2 (401), and support plate 3 (404) are all equipped with guide rails, which are detachably fixed to the support plates by bolts. The guide rails provide sliding mounting channels for electrical components, allowing components to be directly slidably mounted or removed along the guide rails without having to move the entire support plate, thus reducing the difficulty of component replacement.

[0022] The working principle of this utility model is as follows: First, determine the installation location of cabinet 1 based on the usage scenario, and ensure its stability through the overall frame of cabinet 1. Fix the support frame 2 inside cabinet 1 as the core load-bearing structure; then, along the rear side of the support frame 2 from top to bottom, fix the rear side panel 105, rear side panel 2 104, and rear side panel 3 103 in sequence with bolts. The bolt connection ensures that the side panels are firmly installed and also leaves room for subsequent disassembly.

[0023] On the front side of the support frame 2, I-frame 1 301 and I-frame 2 302 are installed at positions corresponding to rear side plate 105 and rear side plate 3 103. The I-frames are fixed to the support frame 2 with bolts, providing a precise installation reference for the connecting assembly 4. The side of I-frame 1 301 closest to rear side plate 105 is fixed with sheet metal part 303 by bolts, enhancing the structural strength at the connection between rear side plate 105 and I-frame 1 301 and preventing deformation caused by stress concentration.

[0024] Next, install the connecting component 4. Fix the left and right sides of the support frame 304 to the support frame 2 with bolts to ensure the overall stability of the connecting component. Fix the support plate 3 404 to the upper part of the support frame 304, and install the U-shaped parts 403 on the left and right sides of the lower part. Add multiple sets of support columns between the left and right U-shaped parts 403 to enhance the load-bearing capacity of the U-shaped parts 403. Then, connect the upper support bending plate 402 to the fixing part 1 405 on the front side of the rear side plate 2 104 with bolts, and connect the lower support bending plate 402 to the fixing part 2 306 on the front side of the rear side plate 3 103 with bolts. At the same time, use pins to connect the U-shaped parts 403 to the fixing part 1 405, to achieve double fixation between the support plate 3 404 and the rear side plate 2 104, and between the support plate 2 401 and the rear side plate 3 103.

[0025] Finally, cable trays are installed on the left and right sides of the support frame 2 using plastic clips to neatly lay cables; guide rails are fixed on support plate 1 (305), support plate 2 (401), and support plate 3 (404) with bolts to complete the foundation construction for the installation of electrical components.

[0026] During normal operation, the double-layered doors of cabinet 1 are closed, forming double protection to effectively block external dust and moisture from entering and protect the internal electrical components. The electrical components are installed in layers on support plate 1 (305), support plate 2 (401), and support plate 3 (404). Each support plate is rigidly connected to the rear side plate and support frame 2 through connecting components 4, ensuring that the components remain stable under equipment vibration.

[0027] Cables are laid out in an orderly manner through cable trays on both sides, with the opening covers of the cable trays closed to prevent cables from becoming tangled. The guide rails slide with the components, ensuring that the components are firmly installed and providing sliding space for future replacements. At this time, the support bend plate 402, U-shaped part 403, and support column of the connecting component 4 work together to distribute the load of each support plate evenly to the support frame 2. The overall structure has strong resistance to deformation, ensuring long-term stable operation of the equipment.

[0028] When maintenance is required, targeted operations can be performed on the faulty parts without disassembling the entire cabinet. If only the components on support plates 305, 401, and 404 need to be inspected, simply open door panel 101 and door panel 102 to expose each support plate. If components need to be replaced, use the guide rails on the support plates to slide along the guide rails to remove the old components and install the new components without loosening the connection between the support plates and the cabinet.

[0029] If the fault is located in the area corresponding to the rear side panel 2 104, first remove the connecting bolts between the upper support bend plate 402 and the fixing part 1 405, then pull the handle of the release pin to release the connection between the U-shaped part 403 and the fixing part 1 405. The support plate 3 404 and the support frame 304 can then be pulled outwards as a whole to expose the rear side panel 2 104 and the surrounding wiring. If it is necessary to inspect the inside of the rear side panel 2 104, simply unscrew the fixing bolts between it and the support frame 2 to disassemble the rear side panel 2 104 separately.

[0030] If the fault is located in the area corresponding to the rear side plate 3 103, remove the connecting bolts between the lower support bending plate 402 and the fixing part 2 306 to separate the support plate 2 401 and the rear side plate 3 103, and pull out the support plate 2 401 separately; if the rear side plate 3 103 needs to be repaired, unscrew its fixing bolts to disassemble it.

[0031] If the fault is located in the area corresponding to the rear side plate 105, simply unscrew the fixing bolts between the rear side plate 105 and the support frame 2, and remove the rear side plate 105 to expose the deep structure. The support plate 305 is connected to the rear side plate 105 through the fastener 306, and can be disassembled and repaired simultaneously.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
